How not to Specify Initial and Boundary Conditions.

[cdelv]

Many times we don't know the initial or boundary conditions. Fortunately, PINNs can work without them. To ensure the closure of the problem one can add some experimental data to the training.

I tried many ways to skip the definition of the Boundary and/or Initial conditions without success. Does someone know how to do this?

See https://deepxde.readthedocs.io/en/latest/modules/deepxde.data.html#deepxde.data.pde.PDE

"Use [] if no boundary condition."

I see, thanks. In the number of points should I just put None?

Use 0
